For single sensor system, information transmitted in wireless networks will appear the phenomenon of delay, out-of-sequence even dropout, so that the process center cannot receive and handle with the information promptly and effectively. Similarly, this situation also exists in the multi-sensor system where the information needs to be transported by wireless networks, even more severe. As a result,...
Sensor data, which are transmitted from local sensors to the central processor, often appear various communication delays because of the uncertain communication channel and various disturbances. Thereby, optimal "Out-of-sequence" Measurements (OOSM) fusion has been presented and attracts plenty of attentions. The OOSM scenario can deal with the delayed fusion problem, but it inevitably comes...
In network, randomly time-delayed or time-tagged situation often occurs, when data or signal is transmitted through network. On the basis of this case, this paper studied the filter design for a dynamic model with one-step sensor delay. First, rewrite the previous dynamic model into a new one by using the method of augmenting state, in order to compensate for the deficiency existing in previous algorithms...
For the nonlinear multisensor dynamic system, a new nonlinear data fusion algorithm is put forward based on filter step by step and strong tracking filter (STF) in the case of that there exist in mild transmission delay and the delay can happen while the measure data is propagated by local network from each local observation site to central processor. Suppose that the estimate and its covariance is...
